There are certain absolutes - the Incarnation, the Atonement, regeneration, sanctification, the doctrine of sin and of the devil, and the doctrine of the Second Coming. And as we believe and understand and practice these things in our relationship to God, in our relationship to one another as Christians, and in our relationship to the world that is outside, the joy will remain in us. Indeed, it will increase and continue, and at the end we shall find ourselves standing in His holy presence with joy unspeakable and full of glory. (pg. 40)
